Hey guys,
My PC will shut off within five minutes from boot randomly, no "Windows has encountered an error" message or anything. Just turns right off. When I try to turn it back on, I'll get a beep, the fans will start up, and after about five seconds it will turn off again, and I'll have to give it an hour before trying again (which will just give me five minutes).
In the limited time I have to look around before it shuts down, I've noted HWMonitor has my CPU temp climbing steadily up to 89*C (yes, Celsius) and then it always shuts down right as it is about to hit 90*C.
I've had the PC for about a 16 months, custom built. I did a check of all my fans to make sure they're running, cleaned out the dust, and removed and re-applied thermal paste (correctly) to the CPU. I believe it's an overheating issue and not a power supply or motherboard issue as can sometimes be the case, but I don't know for sure and would like some help/advice on what to do next. Thank you for your help, specs below!
